Interestingly, Haibane Renmei evokes many of the themes of the Prisoner, the most obvious being the parallel between Glie and the Village, and the Wall and the Rover preventing escape. I haven’t seen enough of The Prisoner to really comment in more detail.

I also note that the television show Lost seems to be deliberately evocative of aspects of The Prisoner as well. I don’t follow Lost as closely as I’d like either, but maybe someone else can comment.
